How do you get to Iwakuni Japan from Tokyo Japan?

It takes 6 hours by bullet train (plus another hour to get you from Narita airport into central Tokyo) pand will run you about $250 each way. You can also fly to Hiroshima and then take the train from there, which will significantly reduce the time but won't be cheaper since no discount airlines serve Hiroshima (only the very expensive ANA and JAL). One option might be to take a discount flight to Fukuoka on Skymark Airlines and then backtrack by train to Iwakuni.
